Muskegon County Sheriff’s Lt. Shane Brown said the investigation into the 3 p.m. accident is ongoing, but it appears “the fault lies with the bicyclist” and not the driver of the sem-truck.

Tyler James Cumings remained in critical condition early Thursday at Spectrum Health hospital in Grand Rapids, Brown said. He suffered major injuries in the crash, police said.

The crash occurred when Cumings was riding his bike east on Eilers Road when he apparently hit the side of the semi trailer and fell underneath. The impact caused the bicyclist’s shoes and glasses to fly off and land in the road.

Cumings became trapped under a wheel of the semi-truck before being rescued, and then was air-lifted to the Grand Rapids hospital.
